Penultimate Amazing
Perhaps the initial report of a sonar image of the bow visor was mistaken? I'd guess that the interpretation of sonar results still allows for errors, but someone who actually knows something about sonar could convince me otherwise. Anyone here with some knowledge about sonar?
How would Lehtola have known virtually straight away that the sonar image was mistaken, when a sonar image is as good as 'seeing is believing', when as of that time, it was not known 'the bow visor was missing'* and nor had divers confirmed it. So how did Lehtola 'know' the sonar image was a sundry piece of metal plate (that matched perfectly the density, shape and dimensions of the bow visor and was in its intuitively correct place, albeit several metres below the bulbous bow (now upside down)?
*Lehtola's memo showing the sonar image was issued circa 8 Oct and withdrawn circa the 9th. The bow visor was not 'found' by the Swedish/Finnish navy until 18th October. If the bow visor showed up in a sonar image why did Lehtola claim it was still missing ten days before anyone knew it was missing?
